The Genome-Level Survey of the WOX Gene Family in Lour.

Though conserved in higher plants, the WOX transcription factors play crucial roles in plant growth and development of Lour., which shows pioneer position in land ecosystem formation and produces nutritional fruits. Identifying the family genes in is imperative for elucidating its growth and development mechanisms. However, the genes in have not yet been characterized. In this study, by identification 22 genes in based on current genome data, we classified family genes into three clades and nine types with homeodomains. We highlighted gene duplications of , which offered evidences of whole-genome duplication events. Promoter analysis illustrated that cis-regulatory elements related to light and stress responses and plant growth were enriched. Expression pattern and RT-qPCR results demonstrated that the majority of genes exhibited expression in the stem. displayed highest expression across various tissues. displayed a specific expression in the stem. Collectively, our study provided foundations for elucidating gene functions and further molecular design breeding in .
